USG-guided fascia iliaca block outperforms the 3-in-1 technique: A randomized clinical study

Background: Regional analgesia is a popular technique to achieve post-operative pain relief. Both fascia iliaca compartment block (FICB) and “3 in 1” nerve block are two regional anesthetic technique for intraoperative and post-operative pain relief in lower-limb surgeries. Use of a single injection in “3 in 1” block necessitates special skill and nerve sparing. Alternatively, FICB is placed more laterally, thereby improving safety and has emerged as a viable alternative. Aims and Objectives: This study intends to compare the analgesic effects of these two blocks in patients undergoing lower-limb surgeries. Materials and Methods: In the current study, 76 patients with American Society of Anesthesiologists I and II were randomly allocated to 2 groups, Group F and Group B. Group F patients received fascia iliaca compartment block and Group B received “3 in1” block. Patient observed in the post-operative period to determine the duration of effective analgesia from the end of surgery. Results: On comparison, it was observed that the duration of analgesia was significantly higher in FICB compared to “3 in1” block (11.31 h vs. 9.71 h [P=0.00]). Total dose of rescue analgesic required in the first 24-h post-operative period showed no significant difference among two groups. Conclusion: This current study establishes the fascia iliaca block as a safer and more effective alternative to “3 in1” block for post-operative analgesia in lower-limb surgeries.
